Century Prep Series rides are designed to prepare new and/or veteran cyclists to ride the Grizzly Peak Century. We emphasize riding in a group and start with relatively easy routes. To check out the entire series and for more information see our Century Prep Series webpage. Non-members are welcome on all GPC rides, but please note: Because of insurance requirements, we limit participation in GPC rides by non-members to two (2) GPC rides. After you join us for a couple rides, please join the club. Your membership includes excess medical and accident insurance.
This tenth ride in the 2026 Century Prep Series leaves from Sports Bsement Berkeley. Climb Tunnel Road to Grizzly Peak Boulevard, turn left and continue to Spruce. Turn left again and descend back to Sports Basement via Spruce, Virginia and Milvia. Members and nonmembers can all pre-register using the link above to save us time at the start.
This ride is NO DROP. This means nobody will be left behind, no matter their pace or ability. Helmets are required. We look forward to riding with you! Rain cancels. Check this page the day of the ride if weather is dubious.
For all the rides in the Century Prep Series and more information, see our Century Prep Series webpage.

- Make sure you have a copy of the route. I will announce the next few regroups at each regroup.
- Prep your bike for the ride, so we can minimize mechanicals. Check tire pressure and brakes.
- Bring your good vibes and patience! Given the group size and urban route, we will probably go at a slow T pace.
[RWGPS route] Come help me celebrate my 40th birthday with a 40-mile road ride! It will likely be a solid T-pace ride, given my current fitness level and all the urban streets. We will have quick regroups to try to keep us together. Portapotty at the top of Hawk Hill (Mile 10), restrooms and snacks at Larkspur Landing (Mile 25). Note the ROLL time of 9:45am.
Optional cake, food, and drinks at my house El Cerrito's Castro Park, five blocks east of the Ohlone Greenway and a 10-minute ride from either El Cerrito BART stations. If you want to do cake only and no ride, RSVP anyway, and indicate "cake only" as your bike make/model in the RSVP form.
Please RSVP at by Friday, May 15 noon to help my planning.

GPC Route: Bears Loop
Start Location: Orinda - San Pablo Dam Rd and Bear Creek Rd
Mandatory pre-registration
If no riders have signed up by 7 a.m. the morning of the ITT/GPC Pace Ride, it will be cancelled. If there is at least one rider signed up, it will go forward and riders can register online up until 9:50 a.m.
Individual Time Trial
Come test your fitness level and get in a great workout by riding the Bears Loop as a time trial. In the ITT, each person rides at his/her own pace (no drafting) to see how fast the Bears Loop can be completed. It’s a great format for pushing yourself to see how fast you can ride the loop.
Pace Group Ride
Ride the Bears Loop at your normal pace to use it to determine your GPC pace (https://www.grizz.org/rides/ratings.php). Or use this ride to train at a particular pace for an upcoming event.
The first rider is off at 10:01 and a rider a minute after that. For the GPC Pace ride, a pace group can start together, or each rider can rider on their own as the ITT riders do. (Regardless of the format, each rider is timed individually.)
Rider finishing times are usually shared in the ride report email to the club. While it is nice to see what times folks ride, reporting of rider times is optional. Also, the ITT is open to both members and non-members; no need to join as in the past.

Bears Loop
Start Location:
Orinda - San Pablo Dam Rd and Bear Creek Rd
Mandatory pre-registration
If no riders have signed up by 7 a.m. the morning of the ITT/GPC Pace Ride, it will be cancelled. If there is at least one rider signed up, it will go forward and riders can register online up until 9:50 a.m.
Individual Time Trial
Come test your fitness level and get in a great workout by riding the Bears Loop as a time trial. In the ITT, each person rides at his/her own pace (no drafting) to see how fast the Bears Loop can be completed. It’s a great format for pushing yourself to see how fast you can ride the loop.
Pace Group Ride
Ride the Bears Loop at your normal pace to use it to determine your GPC pace (https://www.grizz.org/rides/ratings.php). Or use this ride to train at a particular pace for an upcoming event.
The first rider is off at 10:01 and a rider a minute after that. For the GPC Pace ride, a pace group can start together, or each rider can rider on their own as the ITT riders do. (Regardless of the format, each rider is timed individually.)
Rider finishing times are usually shared in the ride report email to the club. While it is nice to see what times folks ride, reporting of rider times is optional. Also, the ITT is open to both members and non-members; no need to join as in the past.
